Embodiment Construction

[0024]The exemplary systems and methods disclosed herein are suitable for providing a haptic interface for a user. For example, the disclosed systems and methods may capture the haptic feedback from contact with a real surface. The disclosed systems and methods may then reproduce haptic feedback to simulate virtual contact with the real surface. As set forth in further detail below, the exemplary systems and methods capture and recreate haptic feedback by mathematically characterizing the vibrational feel of real and virtual surfaces. They further employ computer-generated vibrations to duplicate the feel of a real surface.

[0025]The exemplary systems and methods are described herein as relating to the capture and recreation of the “feel” of surfaces. One factor that contributes to the feel of a surface is the roughness and / or texture of the surface. The disclosed systems and methods are particularly suitable for capturing and recreating a surface's roughness or texture.

Abstract

Systems and methods for capturing and recreating the feel of a surface are disclosed. A method for capturing a feel of a surface comprises contacting the surface with a handheld tool, recording data measured by the tool, and generating a texture model of the surface based on the recorded data. A method for recreating a feel of a surface comprises contacting a virtual surface with a handheld tool, determining an estimated contact force based on the data measured by the tool, generating a vibration waveform from a texture model based on the data measured by the tool; and actuating at least one actuator of the tool according to the vibration waveform. A system for capturing and recreating a feel of a surface comprises a handheld tool, a storage device, and a processor.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Patent Application No. 61 / 369,254, entitled “SYSTEMS AND METHODS FOR CAPTURING AND RECREATING THE FEEL OF SURFACES,” filed on Jul. 30, 2010, the contents of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to haptic human-computer interfaces, which enable a user to interact with virtual objects through motions and forces. More particularly, the invention relates to “haptography” (or “haptic photography”), which involves using a human-computer interface to capture and recreate the feel of real surfaces.BACKGROUND OF THE INVENTION[0003]The ability to touch the surface of an object allows one to feel and determine a number of structural characteristics about the object, such as its shape, stiffness, friction, texture, or other characteristics. Humans are adept at eliciting and interpreting these feelings, called haptic fee...
